IMPROVED WASHING-MACHINE..

Spet ication forming` part of Letters Patent No. 4,284, dated September 20, 196i.

.To all whom, it 71mg/ concern:

Be it known that I, LUMAN W. COOK, of Dowagiac, Cass county, State of h'liehigan,

l havein vented a new and Improved Vashin g- Machine; and I do hereby declare that the tbllowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specifica tion, in which- A Figure lis a verti` al longitudinal section through my improved machine, showing the vibrating arms in a position for compressing the articles. Fig. 2 is similar view, showing said arms thrown back in a position for receiving articles to be washed. Fig. 3 is a horizontal section of Fig. l, taken in the plane indicated by the red line .r m. Fig. 4 is a transverse section through the machine,taken in the vertical plane indicated by red line y y, Fig. 2. Fig. 5 is a perspective view of one set or series of the compressing arms detached from the machine.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in a novel arrangement of vibrating' jointed arms, having rubbers secured to them, in conjunction with vertical and inclined stationary slats, between which said arms work, the whole being so constructed and so arranged within a box having an inclined bottom that the rubbingarms and jointed vibrating arms will operate alternately upon the articles placed within the box and compress and turn them, at the same time keeping the water in constant and violent agitation, all as will be hereinafter described.

My invention also consists in so applying the jointed arms carrying the beaters or rubbers that they can all be removed from or placed within the wash-box at the same time and with very little trouble, as will be hereinafter described.

-To enable others skilled in the art to make and use my invention, I will describe its construction and operation.

Iu'the accompanying drawin gs, A represents the washbox, which is mounted on legs and provided with removable lids or covers. This box is rectangular in horizontal section, and has one portion of its bottom inclined so as to connect with a narrow horizontal portion of the bottom, as shown in Figs. l and 2. At

the deepest end of the box A there are arranged a number of vertical partitions or narrow boards, a a u, which are set at regular intervals apart across the box. Openings are made through each one ot' the boards a to allow the water in the box A to circulate freely between all the spaces formed between said boards, and near the uppermost forward edges of the several boards a notches are cut to receive a transverse rod, b, to which jointed arms B are pivoted, and to admit of this rod being removed or replaced at pleasure. The arms B, which are equal in number to the spaces between the boards a, are pivoted at their upper ends to the rod b, and when at rest hang down in a vertical position. The thickness ot' the arms B is not su'ticient to allow these arms to rit tightly between their respective boards, as it is intended that these arms shall be allowed a free play or vibration. (Indicated by the two positions in which they are represented in Figs. 1 and 2.) The lower ends of the vibrating arms B are connected to longitudinal arms C by links c, so as to allow a free play at 'said points, and the latter arms are secured at their rear ends to a trailsverse strip, d, and further strengthened by the top strip, d', which latter serves as an abutment for the upright beaters or rubbers, D D. The rear ends of the arms C are supported above the inclined bottom of the wash-box by means of vibrating levers E E, which are pivoted at e to the sides of the box A and at e to said arm C. These two levers E are connected together at their upper ends by a horizontal cross-bar, which serves as a handle by which to grasp and vibrate the leve-rs.

Between each one of the longitudinal arms G is a narrow board, g, and these boards are secured to the inclined bottom of the box A and project upward a sufficient distance to allow the articles being Washed to lie on their edges when the arms B C are in the positions shown in Fig. 2. The upper edges of these boards g may incline toward the upright boards c, or they may incline in an opposite direction-i e., toward the front of the box. The former arrangement is, however, desirable, as the tendency otl the articles will always be to keep in a position to receive the blows of the beaters. Each set of arms B C is in the same place, so that the beaters D, which are secured to the arms C, move up toward the spaces between the boards a, and thus act upon those portions of the articles extending across these spaces; hence there will be no injurious rubbing or beating of the articles washed in my machine.

The object of the raised slats or boards g in the bottom of the box A is to support the articles when the arms B C are moved back, as in Fig. 2, and to allow the arms C to fall beneath them, so that when these arms are again moved forward and upward they will turn the articles, and thus" present at each successive movement new surfaces to be acted upon by the beaters. rlhe longitudinal arms U have two motions-Viz., a back and forward movement-and in connection with this their rear ends rise and fall so as to thrust the articles upward and forward previously to their being acted upon by the beaters. The

moved from the box A vby lifting up the rod b and the levers E out ot' their respective bearings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl 1. The arrangement and combination of vibrating arms B, longitudinal arms C, raised boards g, andv levers E, substantially as described.

2. The application ofthe beaters D to longitudinal swinging arms C, in combination with the divisions ce a g g, and vibrating levers E, substantia'ly as described.

3. The arrangement of the vibrating arms B, longitudinal arms C, and vibrating levers E within a wash-box, constructed substantially as described, in such manner as to adl mit of the ready removal and replacing of said parts7 as herein described.
